IMPROVED HAND-PEGGER.

Specification forming part of Letters Patent No. 50,298, dated October3, 1865.

To all whom it may concern:

Be it known that I, J. HAMILTON BROWN, of Boston, in the county ofSuffolk and State of Massachusetts, have invented a new and usefulImproved Hand-Pegger; and I do hereby declare that the f'ollowing is afull, clear, and

exact description of the construction and operation of the same,reference being had to the v fore the blow is given by the hammer to punch lthe hole for the peg, Fig. 2 representing the parts in therelative position assumed at the endof the blow, or when the awl anddriver d is'bnried to its full extent in the leather, and Fig. 3representing the parts in the relative position assumed after the blowhas been struck and the plunger has been thrown up by theretracting-spring f, the awl and driver d being also raised by a catch,F, into the position to be forced down to drive the peg into the holejust made for its reception.

Like parts are indicated by the same letters in all the drawings, whichare full-sized.

The nature of my improvement consists in so constructing a pegging or ahand-pegging machine that a single blow of the hammer will punch thehole and drive the peg, the latter operation being performed by meansot' the recoil of a spring whichhas been compressed by the blow of thehammer, the said spring being held compressed by means of a catch untilthe plunger has nearly reached the limit of its upward motion, havingraised the spring and the awl and driver with it.

To enable others skilled in the art to make and use my improvement, Iwill now proceed to describe in detail those parts not found in otherhand-pegging machines in -general use and the operation of the same.

A is the hollow case or handle, (the general shape of which is clearlyshown in the drawings,) constructed of cast-iron or other suitablematerial.

B is the plunger, consisting of a hollow cylinder, of metal, fitted soas to slide freely in the case A, its upper end being provided with ametallic cap, O, confined by means of a screw, while its lower openingis contracted at m, so

-as to form a bearing for the shaft J of the awl and driver d. Inside ofthe plunger B is a yloosely-fitting shaft, G, the lower extremity ot'lwhich is provided with a head or fiange, i", to

form an abutment for the spring 7c.

D is a pin passing through the case A and longitudinal slots h in theplunger B and the shaft G. v

E is a ring or washer encircling the shaft G and resting on the pin D,which is fast iu the *case A.

fis a spiral spring encircling the shaft G, its

flower end resting on the ring E and its upper end on the bottom of thecap O. The design of this springfis to throw up the plunger B and itsappendages from the position represented in Fig. 2 to that representediu Figs. l

and 3.

L is a rubber spring on the plunger B below the cap O, the design ofsaid spring being to assist in withdrawing the awl and driver d from theleather into which it has been driven, as shown in Fig. 2.

J is a round metallic shaft inclosed within the plunger B, asrepresented in the drawings, its center being provided with a fixedring, Z, of such a diameter as to just slide with freedom in the barrelof the plunger, while its lower half passes through the contracted opening in in the bottom ofthe same.

7c is a spiral spring encircling the shaft J, its lower end resting onthe ring l and its upper end against the bottom of the shaft G, thepurpose of this spring being to throw the shaft J, with the awll anddriver d, from the position represented in Fig. 3 to that represented inFig. l, to drive the peg.

K is the shank of the awl and driver d and the knife or pegsplitter e,the said shank entering a hole in the end ofthe shalt J, to which it isconfined by means of the pin b, as clearly shown in the drawings. Theend of the awl or driver d. is square, so as to answer the doublepurpose of a punch for making the peg-hole and a driver to force the peginto the hole.

e is the knife or splitter, constructed and arranged, as in severalother pegging-machines in general use, to separate the pegs from thepeg-wood U, which is placed in the grooved guide R and fed along towardand under the knife @and driver d by means of arubber spring,

' S, passing over the pulley T, as in other handpegging machines in use.y

F is the catch by means of which the shaft J -and its appendages areraised from the position shown in Fig. 2 to that of Fig. 3. This catch Fis placed in a longitudinal slot in the plunger B and confined byapivot, g, on which it is free to vibrate. The general shape of thiscatch F is clearlyfshown in the drawings, the inner side ofthe loweren'd being provided with a notch, n, which hooks onto the ring l.

I is a longitudinal slot in the case A for the reception of the catch Fand the spring H. The upper end of this spring is attached to the case Aby means of the screw a, its lower end eX- tending downward so as topress upon the end of the catch F when the latter is in the positionrepresented in Fig. 2 and force the notch n under thering l, so as to bein readiness to raise the shaft J as the plunger Bis thrown up by thesprin g finto the position shown in Fig. 3.

AThe operation of the machine is as follows: The various parts being inthe position represented in Fig. l, the end j of the case A is placed bythe operator over the spot where it is required to insert a peg. He thenstrikes with a hammer upon the top ofthe cap C, there by forcing theparts into the position shown iu Fig. 2, so that the awl d shall punchthe peghole and the knife e shall split a peg (to be next driven) fromthe peg=wood YU. This action of the hammer also compresses the springs fand L, forces the bottom of the shaft G onto the top of the shaft J,thereby driving the latter downward, so that its lower end shall strikeagainst the bottom m ot' the case-barrehcomvthrow the lower lend of thecatch F outward,

so as to withdraw the notch n from under the ring l, when the recoil ofthe spring k will force the shaftJ aud its appendages downward into theposition shown in Fig. l, the end of the driver d forcing the pegbeneath it into the hole previously made by the driver, as de scribedabove. Thus a single blow of a hammer is made to punch the hole anddrive the peg, whereas in all other hand-pegging machines hitherto inuse two blows of the hammer have been required to perform the sameoperation; hence the saving of time and labor effected by my inventionis obvious, enabling the operator to perform the same amount of labor inhalf the time required by other machines for a similar purpose ingeneral use.

Having thus described the construction and operation of rnyinvention,what I claim as new, and desire to secure by Letters Patent, is-

Driving the peg by the reaction of a spring compressed by the same blowthat makes the peg-hole.
